How Digital Images Really Work

We take digital images for granted these days – you're looking at dozens right now. But when you stop and think about how the 3D world can be represented so neatly by 1D data stored on a hard drive, it's really utterly amazing.

In this video, Mike Pound explains how digital images really work. They're perhaps not as fluffy and user-friendly as you might think, at least at the computer-level: they're not neatly stored as a 2D matrix, but instead as a long list that goes on and on and on and on. Anyway, over to Mike to explain how all these images are really stored. [Computerphile]
